Claims
What is claimed is:
1. An adapter comprising: a rail having one end secured to a stock;
a groove structure comprising a groove on a bottom, a socket at a
forward end of the groove, a transverse channel through the socket,
a first side surface of the groove structure, and an opposing

transverse channel, and a limit member on the bottom of the groove
structure; a lever pivotably secured to the groove structure and
comprising a handle; and a sliding member disposed in both the
transverse channel and the socket and comprising a projection at
one end, a shoulder adjacent to the projection, a receptacle at an
other end, a biasing member disposed in the receptacle, and a slot
perpendicular to the receptacle and communicating therewith;
wherein a pin is disposed through the pin hole and the slot to
anchor the biasing member between the pin and a bottom of the
receptacle; wherein in a locked state, the shoulder is disposed in
the socket to lock the rail in the groove, an other end of the
sliding member is projected out of the groove structure, the
projection is retracted into the channel and is pressed by the
handle, and the biasing member is compressed; and wherein in an
unlocked state, the handle is stopped by the limit member, the
projection is pushed outward by the biasing member with one end of
the slot contacting the pin, the shoulder is not disposed in the
socket, and the rail is unlocked.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to adapters and more particularly to an
adapter for attaching a detachable stock to the firing mechanism
and the barrel of a firearm.
2. Description of Related Art
Detachable gunstocks are well known. However, conventional adapters
for attaching a detachable stock to the firing mechanism and the
barrel of a firearm are not reliable in use. It is often that the
firing mechanism and the barrel of a firearm are disengaged from
the stock when a law enforcement officer holds a firearm in
action.
Thus, the need for improvement still exists.
SUMMARY OF THE INVENTION
It is therefore one object of the invention to provide an adapter
comprising a rail having one end secured to a stock; a groove
structure comprising a groove on a bottom, a socket at a forward
end of the groove, a transverse channel through the socket and both
side surfaces of the groove structure, a pin hole through the
transverse channel, and a limit member on the bottom of the groove
structure; a lever pivotably secured to the groove structure and
comprising a handle; and a sliding member disposed in both the
transverse channel and the socket and comprising a projection at
one end, a shoulder adjacent to the projection, a receptacle at an
other end, a biasing member disposed in the receptacle, and a slot
perpendicular to the receptacle and communicating therewith;
wherein the pin is disposed through the pin hole and the slot to
anchor the biasing member between the pin and a blind end of the
receptacle; wherein in a locked state, the shoulder is disposed in
the socket to lock the rail in the groove, an other end of the
sliding member is projected out of the groove structure, the
projection is retracted into the channel and is pressed by the
handle, and the biasing member is compressed; and wherein in an
unlocked state, the handle is stopped by the limit member, the
projection is pushed outward by the expanding biasing member with
one end of the slot contacting the pin, the shoulder clears the
socket, and the rail is unlocked.
The above and other objects, features and advantages of the
invention will become apparent from the following detailed
description taken with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 to 7, an adapter for attaching a detachable
stock 1 to the firing mechanism of a firearm in accordance with the
invention comprises the following components as discussed in detail
below.
A rail 4 has one end attached to the stock 1. A groove structure 10
comprises a bottom groove 11, a socket 13 at the other end (i.e.,
open end) of the groove 11, a transverse channel 12 through the
socket 13 and both side surfaces of the groove structure 10, a pin
hole 14 through the channel 12 at the other end of the groove
structure 10, a lug 15 at the other end of the groove structure 10
opposite to the hole 14, a hole member 16 through the lug 15, a
limit member 17 formed on the bottom of the groove structure 10
adjacent to the lug 15 and opposite to the pin hole 14, and a pin
18.
A lever 3 comprises an enlarged head 36, a handle 31, and a
partially threaded pivot 32 inserted through the hole member 16 to
be pivotably fastened by a washer 34, a C ring 35, and a nut 33. An
elongated sliding member 2 is disposed in the channel 12 and the
socket 13 and comprises a cylindrical projection 21 at one end, a
shoulder 23 adjacent to the projection 21, a receptacle 24 at the
other end, a helical spring 25 disposed in the receptacle 24, and a
slot 22 perpendicular to the receptacle 24 and communicating
therewith. The pin 18 is driven through the pin hole 14 and the
slot 22 to anchor the spring 25 between the pin 18 and a blind end
of the receptacle 24.
As shown in FIGS. 2 and 5, in a locked state the shoulder 23 is
disposed in the socket 13 to lock the rail 4 disposed in the groove
11. Also, the other end of the sliding member 2 projects out of the
other side of the groove structure 10, the projection 21 is
retracted into the channel 12 by pivoting the handle 31 to press
thereon, and the spring 25 is compressed (i.e., energized).
As shown in FIGS. 3 and 6, in an unlocking operation, a user may
clockwise pivot the handle 31 180-degree until being stopped by the
limit member 17, the projection 21 is pushed outward by the
expanding spring 25 until one end of the slot 22 contacts the pin
18, and the shoulder 23 clears the socket 13. The rail 4 is
unlocked and thus the stock 1 attached to the rail 4 is unlocked.
Thereafter, the user may detach the stock 1 from the firing
mechanism and the barrel of a firearm.
While the invention has been described in terms of preferred
embodiments, those skilled in the art will recognize that the
invention can be practiced with modifications within the spirit and
scope of the appended claims.
